采用数值三维盆地模型，结合Groningen台地、lauwerssee海槽、Friesland台地和Lower Saxony盆地四个主要地质构造元素，重建了荷兰东北部陆地的埋藏和温度历史。结构框架基于最近公布的开放获取深度表面数据；利用28口井的公开温度和镜质组反射率数据来评估埋藏和温度历史。给出了四种模拟埋藏史和构造元素的成熟度演化。利用最新发表的动力学和文献数据，模拟了石炭系、侏罗纪和白垩纪主要烃源岩层段的生烃过程。模拟结果表明，lauwerssee海槽和下萨克森州盆地的古生代沉积演替的现今温度和成熟度最高，其中埋藏最深。石炭-二叠纪和三叠纪-侏罗世是深埋和隆升的两个主要阶段。这两个层段对古生代烃源岩干酪根的成熟转化均有较大影响。中生代组模拟成熟度最高的是下萨克森州盆地盐底辟之间的洼地。在中生代的两个主要烃源岩层段中，白垩系威尔登页岩产烃时间为晚白垩世。
Numerical 3D basin modeling is used to reconstruct the burial and temperature histories in onshore northeastern Netherlands, incorporating the four main geological structural elements Groningen Platform, Lauwerszee Trough, Friesland Platform, and Lower Saxony Basin. The structural framework is based on recently published open access depth surface data; public temperature and vitrinite reflectance data from 28 wells are used to evaluate burial and temperature histories. Four modeled burial histories and the maturity evolution of the structural elements are presented. The hydrocarbon generation in major source rock intervals in the Carboniferous, Jurassic, and Cretaceous is simulated using recently published kinetic and literature data. Modeling results indicate highest present-day temperatures and maturities of the Paleozoic sedimentary succession in the Lauwerszee Trough and the Lower Saxony Basin, where the deepest burial occurred. Two major phases of deep burial and subsequent uplift occurred in Carboniferous to Permian times and from the Triassic to the Jurassic. Both intervals strongly influenced the maturation and transformation of kerogen from Paleozoic source rocks. The highest modeled maturities of the Mesozoic groups are observed in depressions between salt diapirs in the Lower Saxony Basin. Out of the two major source rock intervals within the Mesozoic, the Cretaceous Wealden Shale generated hydrocarbons from Late Cretaceous times.
